VENT FOR BARRELS.

SPECIFICATION forming part of Letters Patent No. 647,488, dated April17, 1900. Application tied July 21,1899. sain no. 724,593. (No model.)

To @ZZ whom t may concern.-

Be it known that we, HENRY FUNK and KURT TsoHIPKE,citzens of the UnitedStates, and residents of New York city, New York, have invented certainnew and useful Improvements in Vents for Barrels, of which the followingis a specification.

This invention relates to an Iimproved vent for beer-barrels, which isso constructed that the contents of the barrelsmay be subjected eitherto the pressure of the atmosphere or of compressed gas and that anyaccumulated gases may freely escape from the barrel.

In the accompanying drawings, Figure l is a longitudinal section of ourimproved vent; Fig. 2, a similar section, partly in side View, showingthe cock in a different position; and Fig. 3, a cross-section on line 33, Fig. 2.

The letter u represents the casing of the vent, provided with thetubular shank d', adaptedto be driven into the keg A. .Within atransverse bore of casing a is rotatably seated a two-way cock b, packedat b b and adapted to be turned by means of a handle b2. The cock b isprovided at each end with an outwardly-openin g aXialbore or duct c andc', that may be placed in communication with the bore of shank a bymeans of the transverse ducts c2 c3, set at about right angles to eachother, so that it'vthe passage o o2 communicates with the interior ofthe keg the passage c' o3 is shutoff, and vice versa.

One threaded end b3 of cockb carries anut d, which, cooperating with ashoulder h4, holds the cock and packing to its seat. A tapped cap c,having a perforation @'in its body and perforations c2 in its flange,engages the end of thread b3. This cap holds to its seat a disk valvef,perforated at ff out of alinement with the perforation e' of the cap andplaced opposite to a chamber or enlargement c4 of duct c. The oppositeend of cock b is tapped for the reception of a threaded nipple g,adapted to be connected by means of a coupling h to a cylinder t, (shownon a reduced scale,) containing carbonic-acid gas, compressed air, orany other gas under pressure. The inner end of nipple g holds to itsseat a disk valve j, perforated atjj and placed opposite to a chamber orenlargement c5 of duct c. A

The operation is as follows: It neither atmospheric air nor gas underpressure is to be admitted to the keg, the cock is so turned that bothof the ducts c2 c3 are out of communica- 'tion with the shank a'. If gasunder pressure is to be admitted, the cock is so turned that the duct cc3 is brought into communication with the shank, while duct c c2 isdisconnected, Fig. l. .If atmospheric air is to be admitted, the cock isso turned that the duct c c2 is brought into communication with theshank, while the duct o c3 is disconnected, Fig. 2. By slightlyunscrewing the cap e confined gases will be allowed to escape from theinterior of the keg through passage c2 o, chamber c4, and theperforations e2 of the cap-flange. Thus it will be seen that in our ventthe cock can be so manipulated that either natural or artificialpressure may be obtained at will, that the conned gases may readilyescape, or that all exterior communication with the contents of the kegmay be shut oft'.

1. In a vent for barrels, the combination of a casing with a rotatablecock having a pair of ducts that open into the casing at differentangles, a valve arranged within each of the ducts, and means forconnecting one of the ducts to agas-cylinder, substantially asspecified.

2. In a vent for barrels, the combination of a casing with a rotatablecock having a pair of ducts that open into the casing at differentangles, ,a valve arranged within each of the ducts, a perforated capengaged by one of said valves, andv a nipplev arranged opposite to theother valve, substantially as specified.

3. In a Vent for barrels, the combination of a casing with a rotatablecock having a pair of ducts that open into the casing at differentangles, a valve arranged within each of the ducts, a cap having aperforated body and a perforated flange engaging one end of the casing,and a 'nipple engaging the other end of the casing, substantially asspecified.

4.. In a vent for barrels, a casing a, having tubular shank a', combinedwith a rotatable cock b, having shoulder b4, thread b3, and ducts c, c2,c', c3, and with a pair of valvesf, j, nut d, perforated cap e, andnipple g, sub; stantially as specified.
